I wasn't sure this generic yellow sill seal from TVM Building Products would be what I wanted, but after ordering a roll to compare against the usual DOW Blue sill seal, I am pleasantly surprised that I actually prefer it and the best part is that it is about half the price of the blue here on Amazon. I haven't compared to locally source building supply outlet prices, but at roughly $8.50 per roll at the time of this review I feel its a good price.The fluted bottom side design of the foam seal helps it to lay flat while conforming to variances in the concrete. I think it does a great job at that. If your slab has greater than 1/8' dips and sags neither product will fill that void. You may want to add a caulking product to supplement. 2 or 3 (3/8") thick lines laid down under the sill seal can fill those.When placing the seal over anchor bolts I found that a small x-slit allows it to slide down over the bolt. You can follow up with a circular round cut if you want. On windy days it may want to blow around out of alignment. A little caulking under it can help with that too.The blue and yellow seem to be made of exactly the same material. It stretches and compresses the same. I will say that the one down side to the fluted design is that it can tear easier at the thinner fluted parts. You just have to treat it a little more carefully.You can butt or miter the corners. I overlap them then cut thru both at the same time to get an exact miter. I do add caulking sealant at the joints. I come back and caulk seal the interior and exterior edges of the bottom plate to the slab later to keep insects out. Whether you go with this foam seal or a fluid applied sealant, it is a great way to transition from concrete to wood.Its alway fun to get out of the foundation stage and on to framing. Hope your project goes well.** Update - I did find the blue stuff available at a blue big box store for $7.50 per roll and the 3.5" for $6.50 per roll. That makes it a same or slightly better value. Just wanted to update and mention this fact.

Works as it should

These were just what I ordered. They are what the pros use.

Please take out the picture of two rolls sill seals, it’s false advertising, yes if you read the fine print you only get one, but when people are in a hurry and U need to look at the picture to the order real quick and realize when it comes that u only get one roll, sux they were sold out at my store so I was forced to order online for a job, guess I won’t make that mistake again, I thought for that price it must definitely be for 2, overpriced by $8-$10 from my local Home Depot and hardware store

No problems with this one. Plenty of sizable ribs to do the intended water seal on a typical semi-flat concrete base.

It works could be thicker

Excellent results on my room addition.

It shows 2 rolls but you only get 1. Nothing wrong with the product beyond that.
